Initially, an invasive recipe was proposed: the system should be flushed to remove any traces of the old R12-specific mineral oil, the compressor and expansion valve should be replaced with R134a-specific versions to perform correctly, and the old hoses should be replaced with 134a-specific barrier hoses to forestall leakage. Any old black o-rings should be replaced with R134a-compliant green o-rings. Of course, the receiver/drier needs to be replaced, as it does any time an A/C system is opened. A set of R134a-specific charging port adapters should be installed to eliminate the possibility of refrigerant cross-contamination. The compressor should then be filled with R134a-specific oil (usually PAG oil) and the system evacuated and recharged.
R1234yf is a hydrofluoroolefin (HFO) refrigerant. HFO refrigerants are composed of hydrogen, fluorine and carbon atoms, but contain at least one double bond between the carbon atoms. Due to its composition, R1234yf does not damage the ozone layer or has minimal global warming impact. You do not need a ARCTick refrigerant handling licence or a refrigerant trading authorisation to handle, sell or store this refrigerant.
The law against "unlicensed" refrigerant handlers (whatever that means) does not specify any penalties, it just says it is "prohibited", so from a legal standpoint it is an unenforceable law. In order for a law to be prosecuted it must have a penalty specified, otherwise it is moot in court. For this reason, noone has ever been indicted for violating this so-called "prohibition".
A journey refrigeration mechanic license allows you to install, repair, or alter refrigeration or air conditioner equipment. Your license must be matched to the type of refrigerant you work with:
A refrigeration operating engineer license limits you to working on systems in specific buildings that are owned or operated by your employer. You need a refrigeration operating engineer license if:
Question: Do businesses need to have a Department of Agriculture, Trade and Consumer Protection (DATCP) mobile air conditioning license to install and repair mobile air conditioning systems, or any other business license?
The usual leak location protocol involves filling the system and trying to determine where it's coming out, either with an electronic detector wand or with a UV light (which requires putting dye in with the refrigerant). You can get a can of refrigerant (R134a anyway, you need a license to buy R12) and a UV light at a parts store and look for the leak yourself. I've done this to see what I'm in for in terms of a repair bill. A leaking hose in the engine bay might be an easy fix, but no sign of a leak under the hood can be a bad sign, it makes me wonder if the evaporator under the dash is leaking...lots of labor just getting to the part, there.
Freon is Dupont's trade name for R12 and requires a license to purchase and R134a is Suva. R134a is NOT Freon! Cheapest route is have a professional perform a leak test to determine where it's leaking. It may be as little as a $2 seal leaking and you just pay to have it replaced, the whole system vacuumed down and new refrigerant.
It can be a few hours worth of work, or more, depending. You have to recover the refrigerant, do the change-out, pressure test for least 30min, pull a vacuum (least 30min usually), then weigh in the charge. This isn't something I recommend the average DIY try to do. You need epa certification to legally handle refrigerant. You need a recovery machine. Oxy-acetalyne torch with brazing rods. Tank of dry nitrogen. Vacuum pump. Refrigerant scale.
Your scale reads oz? Because all machines I've worked on have the weight of the charge listed in oz, or lb and oz. Recovery machines are fairly expensive. And require a recovery tank. Problem is that refrigerator doesn't hold alot of refrigerant. So you're going to lose a noticeable amount when you recover, as there's going to be some left in the machine after recovery that there's really no way to force into the tank. So you'll need virgin refrigerant on standby to make sure you get a full charge. Also, before recovery make sure your reco tank has been pulled to a hard vacuum to prevent contamination.
You don't have to be registered with the state to work on your own equipment in the USA. However it is illegal to access n a refrigerant system without proper epa certification. For something like this class 1 is all you need. Standard hvac systems require class 2, above 50lbs refrigerant requires class 3.
It's a R134A system which he stated in the question and he is not required to recycle or have a license to service or repair the sealed system in the United states. You can buy the refrigerant off the shelf in Walmart or any parts store.
Sellers might require proof of the EPA 609 certification needed to service refrigerant in cars. Certified technicians ensure that correct measures are taken to avoid Freon escaping into the atmosphere.
R-1234yf is available in eight-ounce cans and does not require an EPA J609 license to purchase. If a shop is purchasing a 10-lb. cylinder, they will need an EPA 609 certification. The cost of an eight ounce can be in excess of $40 and a 10-lbs can cost between $700 to $800 retail. Prices were predicted to decrease as demand increased, but that has yet to happen.
To handle R1234yf, a shop will need a new recycle and recovery machine. The new machines are able to do two things some older machines could not according to SAE J2843. First, new machines can detect the type of refringent that is in the system and it if is a blend. This is very important because of the price of R1234yf. Second, new machines can test the integrity of a system without wasting refrigerant.
Technicians who have previously serviced R-134a equipped vehicles need to be aware of new safety requirements, such as new A/C service cart features, refrigerant identification standards, as well as a vacuum decay test.
The seller does not need to see a Section 608 or Section 609 technician certification card. However, it is a good idea to get a written statement certifying that the product will be resold. The statement should include the business name and address of the wholesaler. Sellers of refrigerant are legally responsible for ensuring that their customers are allowed to purchase refrigerant, either for resale or that they employ a certified technician.
R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The biggest difference between the two is that R1234yf is mildly flammable and does require special handling. Diagnosis of the air-conditioning system can be done in the same way as with R134a. However, you will need different recovery machines and other equipment to handle R1234yf. Some recovery machines are equipped for both R134a and R1234yf. These machines will be equipped with automatic refrigerant detection. To further help avoid confusion, ports for R1234yf systems are a different size. Unlike when R12 was changed to R134a, you cannot retrofit to use R1234yf.
Make sure that you check for vehicle labels and OEM information to ensure the correct type of refrigerant is being used. Different refrigerants require different handling and storag precautions, oils, and A/C equipment. Make sure that you have the training needed to handle whichever refrigerant you are required to use.
HVAC Freon recharge costs $100 to $320 for R410A refrigerant or $180 to $600 for R22 Freon. An HVAC system should never need more Freon unless the system has a leak or the recharge is part of a repair. Hire a licensed HVAC technician to locate and repair any leaks before refilling the refrigerant.
Recharging a home AC takes 1 to 3 hours, depending on the AC's size and pounds of refrigerant needed. Refilling one pound of Freon takes 5 to 10 minutes, and AC units need 2 to 4 pounds of refrigerant per ton.
Home air conditioners never need to be recharged unless there's a leak in the refrigerant system or after AC repairs that require a Freon refill. If an AC shows signs of low coolant, have a professional HVAC technician inspect the system for refrigerant leaks.
You cannot recharge your home AC yourself. Under EPA regulations, only a certified HVAC professional can recharge your home's AC unit. Handling refrigerant is illegal without a Section 608 license and EPA-certified equipment.
According to the Canadian red tek sight. It says that you mustrecover the existing charge in the system first.Whether its R12or r134a. Then add the Red Tek replacement. No mixing of refrigerants.If you have a Walmart or auto part stores. You should be able to buythe cans of R134A and recharge the system. The machine used to remove/recover the refrigerant is called a recovery machine. The machine thatpulls the vacuum is a vacuum pump. If the system is empty you can use thered tek kit. If its not empty I would take the red tek kit back and findone of the stores I mentioned and pick up the R134A to recharge.
The Air-conditioning, Heating and Refrigeration Institute (AHRI) is continuing its work with Environmental and Climate Change Canada (ECCC) to secure an essential-purpose permit to allow automatic commercial ice maker manufacturers to continue importing products with R-134A and R-404A after the refrigerants are phased out in Canada Dec. 31. Manufacturers who are not AHRI members need to secure their own essential-purpose permits. 041b061a72
